Mocking static get gorm method in Grails unit test -

I am using Grails 2.3.7. I have a simple person domain object:

  class person {string name fixed constraints = {}}  

and controller:

  @ Transactional (readonly = true) Class Person Controller {Df Index () {Render View: 'Index', Model: [Person List: Personality ())} Display DIF (Long ID) {DF Person = Person. (ID) Render view: 'Show', Model: [person: person]} ...}  

I am trying to write a unit test for the controller show method, but I'm not sure that a static call Person.get (id) returns a value.

Here's my (unsuccessful) attempt:

  import grails.test.mixin * Import spock.lang * @TestFor (Person Controller) @mock (person) class person controller espec specification {Zero "test shows expansion action involves the person provided in the id and model by the load" () {setup: def PersonMockControl = mockFor (person) PersonMockControl.demand.static.get () {int id - & gt; New person (name: "John")} when: "A valid person identity card for show action" Controller Show (123) Then: "There is a model population in which the individual ID loaded by that unique ID is the domain frequency" model.person! = Null model.person.name == "John"}}  

This test fails because the condition model.person! = Null fails. How do I re-write this exam to pass it?

Edit

In this case, I can do the steps by the Test Reicher on a statutory call:

Zero "test Show action loaded person ID and that person is included in the model "() {setup: def p = new person (name:" John ") Save () when: "Idle Show Action" passed to the controller.show (p.id) Individual ID: "There is a model population in which the individual ID loaded by that unique ID is the domain frequency" model.person! = Null model.person.id == p.id However, I really want to understand how to correctly implement person stable ? " Get the method.

Edit

Get the method of my alleged need to be fake Here is another condition for displaying this filter code:

  DIF FITTERS = {Purchase Filters (Controller: "PayPal", Action: "Buy") {after {= New seller payment (payment: request payment, vendor: get vendor (params.buyerId)). Save ()}}}  

I want to test this I'm shaking that this filter expects using the following tests:

  zero "is called the PayPal plugin controller, when it is a seller to make sure to buyFilter's payment Test "() {setup: // How can I return to the seller (params.buyerId) // To save a new seller back to a seller: When with the filter (action:" purchase ") {Admin: By ()} Then: Vendor Payment DhaHPRO, like dot () == 1}  

Needs do not make a person mimetic .get () is a favorite / proper way of grabbing something in an exam by the way you have - You create a domain example, and pass in the controller's action to consume its ID.

However, if you need to duplicate a static method like this, then there are two approaches:

1) mockFor by GrailsUnitTestMixin Use the method provided and then specify the static method like this:

  GrailsMock mockPerson = mockFor (person) mockPerson.demand.static.get () {Long ID - & gt; Note that in your case, the exact parameter type ( does not occur) in the static  fetch  method uses  instead of long  ) So this method was not being used. 
 
 2) Modify the square ' MetaCLASS . Changing MetaCLASS is very discouraged (especially when  @Mock  annotations sets everything for you), and can test leakage (i.e., other tests may be changed to your meta-class The latter will not work properly, unless you restore the original metalex after the exam). 
 
 He said, for acquaintance, the way you will duplicate  .get ()  method: 
 
  Person.metaClass.static .get = {long id - & gt;  
 
 Again, this is considered bad behavior and should be avoided, but you have it there.
